METHOD OF AND MEANS FOR REMOVING ASHES ON BOARD SHIP.

To all whom it may concern:

Be it known that I, EUGENE BROUQUIERE, a citizen of the French Republic, and a resident of Salchan, Hautes-Pyrnes, France, have invented new and useful Improvements in Methods and Means for Removing Ashes on Board Ship, of which the following is a specification.

The present invention relates to improvements in method and means for removing ashes from on board ship and for forcing the same directly into the sea.

The characteristic feature of the invention is that the removing of the ashes and spent fuel is efiected with as little mechanical work as possible and at minimal working ex penses. With the devices of known constructions which serve for the same purpose, the efliciency of the apparatus decreases with the increase of immersion of the ship, while at the same time the working power for operating the device has to be considerably increased. On the contrary, with the apparatus according to the present invention, the efficiency always remains uniform and the apparatus works the better the deeper the ship is immersed.

In the accompanying drawings an apparatus constructed according to the present invention is shown in Figure l in vertical section and in Fig. 2 in side elevation. Fig. 2 represents the continuation of the mechanism at the top of Fig. 2. Fig. 3 represents in vertical section a watertight door used in connection with the apparatus. Fig. 4: rep resents in vertical section and on a larger scale the head-part of the door. Fig. 5 represents in vertical section and on a larger scale the floating valve.

The apparatus consists of the watertight receptacle a of cast iron or sheet steel, the shape and dimensions of which are chosen according to requirement. The receptacle a is suitably fixed in the floor 5 of the boilerroom in such a manner that its lower part projects into the bottom hold of the ship. To

the lower end of the receptacle a, a valve box 0 is fixed which directly communicates with the sea through a tube (Z, on which a safety valve 6 of the Peet or Kingston type, is mounted, the operating rod 7 of which is connected through suitable gearings with the boiler-room so that it can be opened or closed from this room.

The valve-casing 0 contains the automatic Specification of Letters Patent.

valve 9 which is represented in Fig. 5 and which forms one of the main-parts of the present invention. This valve has a conoidal shape and is made of browned aluminium and whose weight and dimensions are such that it is floatable; this valve 9 is hinged to the casing c by an axle and is actuated by means of a flexible rope or cable h of steel wire, which is conducted over suitable guiderollers 2'. The other end of said rope h, which passes through a small stuffing-box filled with anti-friction material and mounted in the wall of the valve-casing c, is attached to a small piston is, which is movably mounted in a cylinder m. A blade spring a is arranged in valve-casing c which is adapted to act against a shoulder 0 of valve 9 In the upper part of receptacle a a watertight door p is provided which is represented in detail in Figs. 3 and 4. This door is operated through the intervention of a rod g which is rigidly connected with the rod 1" of a piston .9 adapted to move in a cylinder 25. WVhen the door p is being lifted, it withdraws in its casing u in the upper end of which the rod 9 is guided in a stuffing box '2). The rod g has a horizontal bottom end a (Fig. 4), which engages with a suitable hollow of the upper end of the door 79. This hollow is sufficiently large to allow the displacement of rod (1. For well packing the door against the boiler-room, gaskets a: of a suitable elastic material are provided at those parts of the door which are in contact with the wall. The door 79 further is provided with two inclines 2 which in coaction with corresponding inclined planes of the lower casing, serve for displacing the door toward the left hand when a further pressure is exerted on rod 9, so that the door closes the opening very tightly. To prevent the gaskets w being torn ofi when the door is being lifted, two blade springs g are provided which press the door away from the wall as soon as the same is lifted, the door being then guided by two ribs to which are provided in the casing to and which have beveled lower edges.

Below the floor of the boiler-room a pipe 3 is arranged which has a cock 4 adapted to be manipulated through an opening in floor 6 from the boiler-room. This cock 4: serves for connecting the receptacle a with the sea. A second auxiliary pipe 5 with cock 6 serves for forcing the contents of receptacle a into the bilge from where it can be removed by pumps.

Above the floor I) of the boiler-room two cocks 9 and 10 and a graduated pressure gage 11 are mounted at suitable places on receptacle a. In the vertical axis of the receptacle a a shaft 12 is mounted wh ch is adapted to be revolved through sultable gearings for rotating the crusher 1 fixed to its lower end.

The apparatus is operated by water under pressure which is supplied to the apparatus by means of pipe 13. The pipe 13 termlnates in the upper part of receptacle a where it is closed by a cock 14; below the cock 14 a tube 15 is branched off which terminates below the piston of cylinder m; above the cock 14 a second pipe 16 is branched off, which serves for conducting water under pressure above and below the piston s in the motor-cylinder 2. for operating the door. 17 isv the outlet for said cylinder. It is obvious that suitable valves are provided on the branch pipes. Said valves can be actuated through the intervention of two rods so that all the valves are simultaneously brought into the position for lifting the piston s or for reversing the motion of the same.

The apparatus works as follows. Presuming the receptacle a to be empty, door 29 andcock 14 closed and the valve 9 pressed on its seat through the pressure of the water arriving through tube (Z. To control this position of the apparatus, in case the pressure gage 11 should be out of order, the engineer has to open the cock 9 before he operates the door 79. It is well to remark that there is no danger of water getting into the ship, even through negligence, as, if the stoke-r should try to open the door 29 without the usual care, this door'will not move for the reason that the engine operating the same has not the power required to overcome the pressure which would be produced by the pressure of the external water upon the entire surface of the door. The engineer manipulates the rod which effects the lifting of the door 7),- after the door has been fully lifted as much ashes and spent fuel are filled into the receptacle a as it can re ceive; whereupon the door 39 is closed and cock 14 is opened so that water under pressure flows into the receptacle. At the same time cock 10 is opened for evacuating the air contained in receptacle a, to be closed again as soon as water flows out. By the inflow of the water under pressure from pipe 13 the pressure in the receptacle is increased so that it becomes greater than the pressure exerted from below against the valve g. At the same time the water under pressure passes under the piston 70 through channel 15 and'displaces the valve 9 from the horizontal into the vertical position (9 in which position it is maintained so that the ashes and spent fuel can drop out of the receptacle into the sea. By operating shaft 12 the cinders are suitably crushed. The pressure in receptacle a being greater than the backpressure in tube d it is evident that the ashes and cinders must fall out through the valve. As soon as the receptacle a has been emptied, cock 14 is closed. Piston 70 which is no longer lifted through the pressure of the water, descends by gravity being assisted by the spring 71, which presses against the shoulder 0 so that the valve gis brought into the intermediate position (9 After the valve has once assumed this position, it will complete its revolution owing to its buoyancy and will soon be pressed again on its seat through the water flowing in through tube cl. After the cocks 6 or 8 have been opened the receptacle is emptied and all parts return to the original position.

What I claim as my invention and desire to secure by Letters Patent is 1. An ash ejector consisting of a watertight receptacle, an automatic hollow and fioatable valve at the lower end of said receptacle, a tube connecting said valve with the sea so that the external water exerts a certain pressure on the valve, means for conducting water under pressure above the automatic valve, a lateral casing for said valve for bringing the valve out of the way of the falling cinders when the same is open, and a watertight door in the upper part of the receptacle for the admission of the ashes, substantially as described and for the purpose set forth.

2. In an ash ejector the automatic floatable valve having a shoulder at one of its edges, :1 blade spring provided in the valve casing for assisting the back rotation of the valve, a piston for opening the valve, means for connecting the piston with the supplypipe for water under pressure, and a flexible cable connecting the piston with the valve, substantially as described and for the purpose set forth.

3. In an ash-ejector having gaskets of elastic material at the parts which are in contact with the wall and means for lifting the door from the boiler-room, consisting of a piston, a vertical rod mounted with slight play in the upper end of the door, curved blade springs for pressing against the outer surfaceof the door and a thickened part with beveled inner surface at the upper end and a beveled lower end of the door, substantially as described and for the purpose set forth.
